Use this page to configure formatting options for Dart files. View the result in the Preview pane on the right.
In this tab choose whether you want to format your Dart code using the dartfmt tool.

Tabs and Indents
|Use tab character|| |
|Smart tabs|| An indentation consists of two parts. One part results from nesting code blocks and the other part is determined by alignment. |
|Tab size||In this text box, specify the number of spaces that fits in a tab.|
|Indent||In this text box, specify the number of spaces (or tabs if the Use Tab Character checkbox is selected) to be inserted for each indent level.|
|Continuation indent||In this text box, specify the number of spaces (or tabs if the Use Tab Character checkbox is selected) to be inserted between the elements of an array, in expressions, method declarations, and method calls.|
|Keep indents on empty lines||If this checkbox is selected, IntelliJ IDEA retains indents on empty lines as if they contained some code. If the checkbox is cleared, IntelliJ IDEA deletes the tab characters and spaces on empty lines.|
Use this tab to specify where you want IntelliJ IDEA to insert spaces automatically. Select the checkboxes next to the description of relevant locations and check the results in the Preview pane.
Wrapping and braces
In this tab, customize the exceptions, brace placement and alignment options that IntelliJ IDEA will apply to various code constructs on reformatting the source code. Check the results in the Preview pane.
Hard wrap at
In this field, specify the number of spaces required to the right of an element. If you accept the Default option then the value from the global settings is used.
Wrap on typing
In this field, specify how the edited text is fitted in the specified Hard wrap at field.
- Default - choose this option to use the Wrap on typing value from the global settings.
- Yes - choose this option to use the value from the Right Margin field.
- No - if you choose this option a line can exceed the value specified in the right margin.
Visual guides In this field, specify multiple right margins. You can leave a default value or enter the number of spaces for your margin. If you want to specify several margins, enter numbers separated by comma.
Keep when reformatting
Use the checkboxes to configure exceptions that IntelliJ IDEA will make when reformatting the source code. For example, by default, the Line breaks checkbox is selected. If your code contains lines that are shorter than a standard convention, you can convert them by disabling the Line breaks checkbox before reformatting.
A wrapping style applies to various code constructs, specified in the left-hand pane (for example, method call arguments, or assignment statements).
|Do not wrap||When this option is selected, no special wrapping style is applied, the nested alignment and braces settings are ignored.|
|Wrap if long||Select this option to wrap lines going beyond the right margin with proper indentation.|
|Wrap always||Select this option to wrap all elements in lists so that there is one element per line with proper indentation.|
|Chop down if long||Select this option to wrap elements in lists that go beyond the right margin so that there is one element per line with proper indentation.|
|Align when multiline||If this checkbox is selected, a code construct starts at the same column on each next line. Otherwise, the position of a code construct is determined by the current indentation level.|
|Select this checkbox to move the specified character or characters to the next line when the lines are wrapped.|
|'else' on new line||Use this checkbox to move the corresponding statements or characters to the next line.|
|New line after ||Select this checkbox to move the code after the specified character to a new line.|
|Special else if treatment||If this checkbox is selected, |
|Variable declarations||Choose one of the following options to configure alignment for equality signs: |
|ES6 import/export|| Align 'from' clauses: When this checkbox is selected, IntelliJ IDEA aligns |
With this option on, IntelliJ IDEA will align the new code on the fly. Existing
Braces placement options
|Braces placement style|| Use this drop-down list to specify the position of the opening brace in class declarations, method declarations, function declarations, and other types of declarations. The available options are: |
|Force braces||From this drop-down list, choose the braces introduction method for |
Use this tab to define where and how many blank lines you want IntelliJ IDEA to retain and insert in your code after reformatting. The results are displayed in the Preview pane.
|Keep Maximum Blank Lines||In this area, specify the number of extra blank lines to be kept after reformatting.|
On this tab, configure the code style for generated code.
